I recommended the Tammi Hartung book in another post. Still love it for basic growing/use info.

If you're into getting serious culinary with fresh herbs, then I also like The Herbfarm Cookbook by Jerry Traunfeld. Most of the recipes aren't for general home cook, more suited to restaurant, but there are bunches of charts on uses of herbs that are very useful, and some basic recipes for such as herbed sauces, creams, sorbets, etc.

But books that provide a good reference are so valuable and make it soooooo easy to access information ---- especially for new herb gardeners.

For 1 all around book, I do love New Encyclopedia of Herbs & Their Uses by Deni Bown. See if you can pick up a used copy. It has both growing and using info - including culinary, medicinal, dyeing, etc. herbs. Having info about more than just your standard kitchen herbs is so wonderful.
